Dear Colleagues,

I have been notified from station BAKO that they installed a Leica AT504 GG antenna with LEIS radome on 1 January, and the antenna height changed to 1.648m.

There is no calibration for this equipment in igs05.atx, and although the IGS Site Guidelines (http://igscb.jpl.nasa.gov/igsnetwork/guidelines/guidelines.html) state (2.1.8) "To use an antenna+radome pair not found in either of these files, contact the CB. A calibration from an independent, recognized laboratory such as NGS (http://www.ngs.noaa.gov/ANTCAL) or Geo++ (http://www.geopp.com) will be required," the CB was not notified in advance of this equipment change.

We understand that a calibration is forthcoming. In the meantime, since site logs may not contain uncalibrated equipment, the revised site log cannot be installed.

Best regards,
Angie
